The current study examined the efficiency of four high-fidelity DNA polymerases—AccuPrime ™ Taq DNA Polymerase, Platinum ® Pfx DNA Polymerase, Q5 ® High-Fidelity DNA Polymerase and KOD FX Neo—for developing an efficient method based on RT-PCR for detecting and identifying DENV in field-caught mosquitoes. Taq DNA polymerase works great for routine applications, but not every application is routine. In heat-activation tests (blue curves), polymerases were heat-treated at 94°C for 2 minutes to dissociate the antibodies from the polymerases. Polymerase Stalling: Many high-fidelity DNA polymerases, particularly those from archaea (e. Pfu Polymerase offers high thermostability, high fidelity, and is ideal for experiments that require high temperatures or high accuracy. (B) a “warm-start” DNA polymerase. The pioneering work of Thomas Kunkel (3) utilized portions of the lacZα gene in M13 bacteriophage to correlate host bacterial colony color changes with errors in DNA synthesis. Figure 4. The first decision you'll probably make is, do you need high fidelity amplification, or standard amplification?

In comparison, libraries amplified by other high-fidelity polymerases displayed a marked bias by underrepresenting coverage of GC- and AT-rich sequences. I understood that Q5 is a newer generation of polymerase (like KAPA Hifi but unlike Phusion, iProof etc). When do you need a High-fidelity Polymerase? The increased accuracy of high-fidelity polymerases makes them much more suitable for sensitive downstream applications than standard Taq polymerase. In this study, fourteen commercially available DNA kits containing polymerase (Table 1) were compared in terms of the PCR-generated artifacts. The ability of DNA polymerases to replicate DNA templates accurately is called fidelity. High-Fidelity DNA Polymerase. If an incorrect nucleotide does bind in the The increased template fidelity of these polymerases can come at the cost of reduced template specificity, and library preparation methods based on the AFLP technique may be particularly susceptible. Unbiased reviews by scientists available at Biocompare. High-fidelity PCR enzymes include proofreading archaeal DNA polymerases (Table 1) and DNA polymerase blends (Table 2). Commercial proofreading DNA polymerases have been obtained from Thermococcus and Pyrococcus species of hyperthermophilic archaea and are classified as Family B-type DNA polymerases13. For standard polymerases, fidelity refers to the ability to discriminate correct vs. Successful PCR depends on two crucial components, a high-quality, thermostable DNA polymerase and an optimized reaction buffer.
